Loooivrorivii naiviivwirniin To all whom t may concern:

Be it known that I, WILLIAM KYLE, a subject of the King of Great Britain, a resident of the city of Bellville, in the county of Hastings, in the Province of Ontario,

Canada, have invented certain new and use-- i y invention relates to improvements in locomotive driving wheels and the object of the invention is to devise an attachment therefor by means of which the connecting rod can be connected to such wheel so that the pull on the wheel will be equa-l, whether taohment thereto.

ig. 2 is a section through the line 2-2 (Fig. l).

ig. 3 is an inverted tion of my attachment. i

ike characters of reference indicate corresponding parts in the different views:

l is a wheel. 2 are the spokes thereof. 3 is my attachment of preferably annular shape and having the inwardly extending web 4 for approximately half the diameter thereof, said inwardly extending web provided with the slots 5 for the reception of the spokes. 6 is a hole in the annular attachment for the reception of the pin for pivotally connecting the connecting rod thereto. 7 is a semicircular plate suitably secured to the web 4 by the bolts and nuts 8 and 9 respectively, the bolts 8 being preferably countersunk into the attachment 3. The attachment is vapplied as follows: The portion 3 is placed on the wheel concentrically with the hub 10, the spokes 2 tting into the slots 5 in the web portion 4 thereof. The semicircular plate 7 is now applied on the inside of the wheel to the plan view of a por- Specication of Letters Patent.

web 4 an'd held in place by threading the nuts 9 on the bolts 8. b

leverage from the point of connection with the annular portion 3 to where the same is connected to the spokes, or in other words the upper half of the wheel. Consequently this will overcome the loss of leverage which occurs in ordinary locomotive wheels when e connection is at the bottom of the wheel. y using my attachment the leverage will be equal and consequently any tendency for the wheel to slip under normal loads will be obviated.

Although I have he remaining part of the wheel, and means .for pivotally connecting the connecting rod to the center of the free portion of the attachment.

.2. The combination with pivotally connecting the connectinfr rod to the center of the freeportion of the attachment.

3. The combination with a locomotive drive wheel, of an annular attachment secured to the wheel for part of its circumference, and means for pivotally connecting the connecting rod to the center of the free portion of the attachment, the said means and the points of connection to the Wheel Wheel.

4. The combination With a drive Wheel, of an annular attachment having an inwardly extending' web for half its circumference', said Web having'a plurality of slots on its inner face for the reception locomotive Y of the spokes, a semcrcular plate, Yloolts extending through the web and through the plate for securing the attachment to such ,spolresyand means for connecting the connecting'rod to the center of the remaining free portion of the Vannular attachment.
